I’d like to create a function that runs only once every time my site is deployed. This function would make some API requests and write the response to a database (Firestore) from which my React app can retrieve and use the data without making additional/unnecessary API calls. After reading the docs I still don’t understand how to implement such a function. Also, since I’d like to update my database once a day, are there any limits to how many times I can deploy my site?
